I, Zombie #16

Gwen, Spot, and Horatio are trapped underground with a horde of zombies -- and unlike Gwen, these are the shambling, feast-on-the-flesh-of-the-living kind! Meanwhile, Gramps the Chimp sets out to find his lost grandson, Amon and Ellie make a startling discovery, and when The Dead Presidents arrive, things get very complicated for everyone's favorite zombie girl detective.
